55. A dog starts at the origin and runs forward at 6 m/s for
1.5 s and then turns around to fetch the ball by
running backward at 7 m/s for 3 s. If the dog runs
back to the origin at 4 m/s, then how much time has
elapsed between the start and when he returns with
the ball?

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
